Bare glass fiber holder

Abstract

A fiber holder is provided which includes first and second holder plates having first and second main surfaces, respectively. The first holder plate includes a first channel insert including a first fiber channel configured to receive a fiber therein, and a first insert channel disposed on the first main surface such that the first insert channel extends through a length of the first main surface and is configured to receive the first channel insert. The second holder plate includes a second channel insert including a second fiber channel configured to receive the fiber therein, and a second insert channel disposed on the second main surface such that the second insert channel extends through a length of the second main surface and is configured to receive the second channel insert. The first and second channel inserts are disposed within the first and second insert channels, respectively.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Application No. 61 / 316,529, filed on Mar. 23, 2010, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field[0003]The present invention generally relates to a bare glass fiber holder, and more particularly, to a large diameter bare glass holder which holds optical fibers having a cladding diameter of about 230 μm or greater.[0004]2. Description of the Related Art[0005]High precision large diameter fibers (LDFs) cleavers have been developed which are designed for cleaving LDFs. An LDF, which typically has a cladding diameter from 230 μm up to 1000 μm or more in diameter produces cleaved angles within 0.5 degrees.[0006]A built-in microprocessor of the cleaver controls all parameters and settings, such as clamping, tension and the exact position and speed of a diamond blade used for cutting or cleaving. This control of sensitive parameters is u...

AI Technical Summary

Benefits of technology

The patent is about a device that prevents the insert from slipping out of a channel. This is useful in situations where the insert needs to be securely fixed in place. The device has two stops, one for each channel, that prevent the insert from moving. The stops are designed to not interfere with the channels, allowing for safe and secure insertion. Overall, this device provides a way to securely hold and prevent movement of the insert in its channel.

Problems solved by technology

However, when the fiber is not coated or jacketed (i.e., when the fiber is a bare glass fiber), it is difficult to clamp and hold the bare glass fiber in the fiber holder without breaking the fiber.

Accordingly, because of the clamping force needed to securely hold onto the fiber, a bare glass fiber often breaks due to the applied pressure.

Furthermore, each time a different sized fiber is used, a different fiber holder must be selected, which is inconvenient.
